While the weather catchphrase of recent winters was the shiver-inducing polar vortex, the buzzword for this winter in the U.S. will be drought.
Significant droughts are already in place over nearly 45 percent of the contiguous U.S., with hotspots in California — where the drought is in its sixth year — the Southeast and
Northeast. With the renewed possibility of a
La Niña emerging in the next couple months, little improvement is expected in most areas; the drought in the Southeast is expected to expand and drought could also emerge in the Southern Plains, according to the most recent
seasonal forecasts from the National Oceanic and Atmospheric Administration.
"The winter forecast doesn't bode well for [California] and many other areas around the nation currently experiencing drought," Mike Halpert, deputy director of NOAA's
Climate Prediction Center, said during a press teleconference.
La Niña is the opposite end of the natural climate seesaw from El Niño; it is characterized by cooler-than-normal ocean waters in the tropical Pacific, while El Niño features warmer-than-normal.
After an exceptionally strong El Niño, conditions in that area of the Pacific have cooled, moving into neutral territory and now "hovering near the La Niña threshold," Halpert said.
